Oceans & seas (salinity comparison): Which of the following seas has the highest average salinity? Assume standard global averages for these enclosed/semi-enclosed water bodies. Choose the correct sea with the highest salinity.

Difficulty: Easy

Dead Sea
Red Sea
Black Sea
Mediterranean Sea

Correct Answer: Dead Sea

Explanation:

Given data

Compare average salinity among Dead Sea, Red Sea, Black Sea, Mediterranean Sea.

Concept/Approach
The Dead Sea is a landlocked hypersaline lake with average salinity ≈30%–34%, far exceeding open seas and semi-enclosed seas (Red Sea ≈4%, Mediterranean ≈3.8%, Black Sea ≈1.8%–2.2%).

Final Answer
Dead Sea
